    Abstract

    This paper presents adsorption isotherms of R-134a (HFC-134a) on highly porous pitch based activated carbon (Maxsorb III) in the temperature range of 5-70 °C and pressures up to 12 bar, using desorption method. The experimental data have been fitted with the Dubinin-Astakhov (D-A) isotherm equation. The adsorption isotherms of R-134a on Maxsorb III obtained from the present study are compared with the adsorption isotherm results of R-134a on similar type of adsorbents obtained by other researchers and they are found to be fairly consistent. The isosteric heat of adsorption of the assorted adsorbent-refrigerant pair has also been extracted from the present experimental data.
